Ask A Scientist: How Do I Use Dendritic Cells for an MLR?

Our resident dendritic cell expert, Benjamin Tjoa, was one of the first scientists in the world to develop dendritic cells for use in cell-based vaccines. Ben has traveled internationally to help labs prepare for developing dendritic cell-based therapies. Monocyte-derived dendritic cells are a hot topic for many of our customers, and Ben has answered countless […]

Useful Tools in Immunology: The Human Protein Atlas

When I need more information on a protein or antibody, one of the first places I turn to is The Human Protein Atlas. It’s a remarkable open-access collection of all known proteins in human cells, tissues, and organs.  When I say remarkable, I mean it. The Human Protein Atlas has amassed detailed information on more […]

In-Depth Guide for Working with Macrophages

Macrophages have many applications in immunology research and can produce a wide range of cytokines and chemokines that can influence the immune response in both mouse and human models.  We’ve compiled an in-depth guide with our best resources for working with macrophages, the “Big Eaters” of the immune system. You’ll get tips for creating and […]

How to Differentiate Monocytes into Osteoclasts

Our contract immunology research team is always looking for a new challenge. So when a customer proposed a project that involved differentiating monocytes into osteoclasts, we said, “Why not!” Fun in the Lab with Monocytes Osteoclasts are macrophages found in bone and are highly specialized myeloid cells that break down and resorb bone tissue, important […]
